The so called temporary embolization by percutaneous injection of autologous clot can be envisaged as the method of choice in selected cases of massive renal bleeding. The goals of this technique are to occlude the bleeding vessels until a satisfactory hemostasis is achieved and to preserve as far as possible the renal parenchyma by adopting a completely reabsorbable embolic material as the autologous clot. After a review of the literature a case is presented where a temporary embolization was performed in a young woman with brisk postoperative bleeding in a solitary kidney. The procedure was successful and the renal function was not impaired.
